OK, I've let my motor run for about 2 hours total time since rebuild, changed the oil twice, and I'm still getting "dust" for lack of a better term, on my dipstick. If I pull the dipstick after I've let the engine run, it comes out clean as a whistle. If I let the engine sit for a half an hour, this dust settles on the top of the dipstick but the bottom is still clean. If I wipe it off and check it again it is clean. Is this normal.

what type of lube did you use to break the engine with?

I'm not positive but it was just an over the counter assembly lube. Will that make a difference? I'll check the tube and let you know.
Thanks for the interest

have you cut your oil filter apart?, if not you should that is the only true way of finding any major wear look for copper or steel particles in the filter

Yes, I cut it apart and it was clean. Not one speck of metal or copper in it.

When breaking in a new motor I've found it helps to let the motor get up to 220 degrees temp. The high temp is good for the bearings to help them take a set.

Are you using synthetic oil? If so use regular petroleum based oil. The synthetic is ok to use, but not until motor is broke in.

Same goes for gear lube. Don't use synthetic on new set of gears.
